Low Temperature Melting Point Frit Glass Powder

Product Overview

Low melting point glass powder is an advanced sealing material introduced by ANYWHERE POWDER researchers, which has a low melting temperature and sealing temperature, good heat resistance and chemical stability, high mechanical strength, and is widely used in vacuum and microelectronics technology, laser and infrared technology, high energy physics, energy, aerospace, automotive and many other fields. This product can be used in the mutual sealing between glass, ceramics, metals and semiconductors. It enables sealing between glass, ceramics, metals and semiconductors. As a new material, low melting point glass powder has been used in some new materials, but the application prospects are far beyond the current encounter, and still need to be explored and expanded by researchers.
